I will kick-off. Look for the movie "Silent Running". Essential terrain in a base or starship is the hydrophonics bay. The Green Bits are not to hard to produce getting plastic aquarium plants from the local petstore. But they would need to be placed in a "plot". For this I would like to use the ramps as they are currently available, but with the option to:

have a "doublewidth" plinth (the pieces you stick underneath the wall that hold the wall and the ramps.

I believe that there were comments made about using re-usable sticky labels to create effects such as battle damage and blood or bodily fluids trails... This could also be a way to create other effects such as structural damage to walls and control panels.
